Subject: Re: OpenCl lib not detected
I always use install method written in /john/doc/INSTALL-UBUNTU.
Yesterday I removed the /john dir and used git clone method for a clean install.
When tried to configure it, I noticed that OpenCL not supported.
I checked the necessary packages as written in INSTALL-UBUNTU, also. Everything were installed.
Now jtR compiled, but I had use these parameters:
"./configure LDFLAGS=-L/usr/local/cuda-11.0/targets/x86_64-linux/lib CFLAGS=-I/usr/local/cuda-11.0/targets/x86_64-linux/include
make -sj4"
without it, OpenCL not supported.
Note: It was a working system before I removed the /john dir and tried to install it again. There was no problem with JtR.
